Be it known that I, HENRY G. TYER, of Andover, in the county of Essex,and State of Massachusetts, have invented a new mode of manufacturingOver-Shoes or Boots, without straps, buckles, buttons, or otherfastenings, whereby the drawing on or pulling o'ofsuch boots or shoes isgreatly facilitated, a smooth and snug fit obtained, and all uglyadditions harboring snow or mud are entirely avoided. Of the drawingsherewith presented- Figure 1 denotesa view of a trapezoidal piece of thegore-cloth to be used in the formation of the shoe.

Figure 2 represents such piece of cloth with cement-applied to it aboutits edges.

Figure 3 is a side view of a shoe provided with elastic gores formed ofelastic cloth anda vulcanizable material, one of such gores being shownat A.

Figure 4 is a longitudinal section of the shoe, showing where theinelastic lining is removed after vulcanization of the shoe, suchVremoval being denoted at B, and for the purpose of enabling the elasticgore to be stretched as occasion may require.

The nature of my invention consists in the insertion of a vulcanizablegore o r gores of elastic material in such part ofthe boot or shoe asmay be most desirable during the construction of such boot or shoe, andbefore its vulcanization; the latter process being applied after theseveral parts composing the shoe are united, the same causing all thevarious pieces to become consolidated, and a perfect boot or shoe, withone or more elastic gores, to be the result.

To enable others skilled in the manufacture of rubber shoes tousc myinvention, I wili proceed to describe the operation, selecting a gaiterboot or shoe as a prominent means of illustration.

I first prepare the lining 0,-(see fig. 4,) of annel or other suitablematerial bycoating the same with a vulcanizable cement of rubberoriother adhesive, vulcanizable compound. After having reduced thelining, or the pieceA composing it, to shape, I draw or place it overalast and insole in the usual manner, so that the cemented side of suchlining may be outward. I next procure a fabric of cloth with certainpeculiarities of manufacture, capable of greatlateral extension,preferring that known as diagonal cloth, in which the threads of thewarp cross tho'se of the filling at acute angles rather than at rightangles, such being as shown in fig. 1. I do'not conne myself to any oneparticular fabric or material, using any, however manufactured orprepared, if elastic or capable of the'necessary extension andcontraction. I proceed to coat the material on one side with avulcauizable rubber cement or composition, taking special care not tostretch the cloth in handling it. I next cut from the cloth so coatedthe insertion or gore-piece, of such shape as may be desirable. 'Next Iapply Indiarubber cement to the bottom and side edges of the gore,laying it thereon about three-eighths of an inch'wide,

`und on the uncemented face thereof, the same being as shown in fig. Y2,in which a a a denote the cement. Next I place the gore in its properposition on the lining, and with a strip of paper or cloth arrangedbetween the gore and the lining in orderto guard against their unionexcept at the ccmentedfedges of the gore in the after pr o cess ofvulcanization'.` Theobject of retaining the lining wholel or uncut atthe gore is to prevent the lateral extension of the gore' when therubber is in a softened state during vulcannation. I next cut from asheet of vulcanizablevrubber or rubber compound, a piece of thesamc'shape as the inner part of the gore before referred to, butsomewhat larger, so that the edges may extend beyond the first piecewhen laid thereon and united thereto. vSometimes I spread a suiii'cientthickness of coating of rubber on the gore lining in the rst instance,

rendering the sheet just spoken of unnecessary, but Iprefer that thelining and sheet gum should be distinct from each other. I nexttakestrips ef thin sheet rubber or rubber compound, say three-eighths ofan inch wide,

and turn and roll over-one edge thereof for binding 'and makingaueatnishientircly'around the top 'of the 'boot and thatof the gore, thisbinding abrding additional strength top-such part of the boot or shoe,it being that which has to resist the heavier strains. I next preparethe""diagonal cloth" or'other elastic fabric which I intendvusingfor theoutside of the gore or' insertion. This I do by cementing it 'preciselyas hereinbefore described for theinner part or lining of the same,andcut it into similar shape to that, taliing particular care in doing sothat the threads of the warp and filling of the two. pieces, when theyare united, bear such relative posi-` tions to eachother as to renderboth pieces capa-ble of extension in the same direction, failing inwhich, the

elasticity ofthe gore or insertion would thereby bein a great measuredestroyed. *After thisoutsideV-piece may have been-securely fastened initsrproper position I proceed to finish the boot or yshoe in suchmanner-"and style as may be required; this, and the subsequentoperation', being well known to India-rubber manufacturers, as well asthe after vulcanization of the shoe or boot in a complete state. Ifinally cut away or remove the lining of the shoe in rear of the gore iuorder to allow the gore full freedom to expandl I do not elaim'broacllythe insertion of an elastic gore in a boot or shoe, such being niiarticle of extensive manufacture at the present time; neither do I claimsimply the formation of' au elastic fabricnsuch being well known, andthe subject of many patents; vneither do -I claim the lining of anIndia-rubber sho'e with ordinary stockinet, such being dailymanufactured; but what I do claimas my invention, and desire to secureby Letters Patent, is Y The new process described of making a vulcanizedshoeV with an elastic gore, the same consisting in the insertion withinthe shoe during the construction of it, and prior to vulcunization ofit, of muslin, stockinet, or othercquivalent fabric, (howercr suchfabric may have been prepared,) in connection with the vulcanizubleIndia rubber or India-rubber compound, placed on or between layers ofthe said fabric, und subsequently submitting .the whole tovulcanization, and to a removal of part of the shoe lining, the Wholebeing substantially as hereinbefore setforth.
